New in the August issue of Physics Today: Sarah Frances Whiting's x-ray photography, bridging the gap between physics and biology, the warmth of wind power, and more physicstoday.scitation.org/toc/pto/73/8 Image
Sarah Frances Whiting and the “photography of the invisible”: A team of women working in the physics laboratory at Wellesley College carried out some of the first successful x-ray experiments in the US doi.org/10.1063/PT.3.4…
Does new physics lurk inside living matter? The link between information and physics has been implicit since James Clerk Maxwell introduced his famous demon. Information is now emerging as a key concept to bridge physics and biology doi.org/10.1063/PT.3.4…
The warmth of wind power: As wind turbines harvest energy, they redistribute heat in the lower atmosphere. Farmers have been exploiting the effect for decades doi.org/10.1063/PT.3.4…

A historian’s dream, the Farm Hall transcripts capture the secretly recorded conversations of Werner Heisenberg and 9 other German physicists discussing the atomic bomb in 1945. So why do scholars disagree on what they tell us? 🧵#histSTM #twitterstorians physicstoday.scitation.org/do/10.1063/PT.…
The Farm Hall transcripts are among the most famous primary sources in 20th-century physics. They document conversations between 10 German physicists suspected of working on an atomic project for Nazi Germany, including Heisenberg, Otto Hahn, and Carl Friedrich von Weizsäcker.
The physicists were rounded up at the end of World War II by Allied intelligence and imprisoned in a luxurious English country mansion called Farm Hall, where their conversations were secretly recorded.

Albert #Einstein’s neat cursive has achieved pop culture status: A letter he wrote featuring the E = mc² equation recently sold for nearly $1.25 million at auction. But Einstein’s handwriting is also a microcosm of his turbulent life, argues @_rdahn [1/5] physicstoday.scitation.org/do/10.1063/PT.…
Einstein actually employed a different type of German handwriting early in his life. Called Kurrent script, it looks quite different than the Latin cursive still taught in some English-language schools today. [2/5]

Credit: Der Damen-Briefsteller, 1866/Public Domain Kurrent script.
Einstein switched from Kurrent script to Latin cursive in 1905—the same year he published his annus mirabilis papers. Part of the reasoning behind his decision was surely practical: Foreign scientists could read German, but they often struggled to read Kurrent. [3/5]

This year's #NobelPrize laureates have received their medals. If the October prize announcements feel like two years ago rather than two months, check out this thread on some of the prizewinning work:
Roger Penrose received half of the #NobelPrize in Physics for his theoretical work on black holes doi.org/10.1063/PT.3.4…
Andrea Ghez and Reinhard Genzel shared half the #NobelPrize in Physics “for their discovery of a supermassive compact object at the center of our galaxy” doi.org/10.1063/PT.3.4…

In a 1794 essay, her first and only publication, Scottish chemist Elizabeth Fulhame postulated the mechanism of catalysis decades before the term was coined and documented metal photoreduction, a process crucial to the development of photography (thread) physicstoday.scitation.org/do/10.1063/PT.…
The essay also addressed a raging debate of the era, on the merits of phlogiston theory. Fulhame used the evidence from her experiments to show that phlogistonists were wrong. Then she showed that antiphlogistonists were wrong too.
Fulhame's essay received glowing reviews in Europe and the US. She was one of the first women elected to the Philadelphia Chemical Society.
